i love the game but im getting frustrated im in the second set of scenes and i cant get the crab over to cut the seaweed, cant find the shell, cant find the purple dot to kill the fish. wth? any one have any ideas or help? or atleast a walkthrough

to get the crab to cut the seaweed, grow his food in the hole, then when the flower grows, pluck the flower without eating the food by accident, then use the flower to lead him into the screen with the bottle.

has anyone played the full version? I can't figure out what to do to get the fish out of the hole where the bottle is flipped upside down. I'm assuming I need to move the bottle/get around it to get the shell
